Abstract
Description
-
- Nonlinearity: A nonlinear model is capable of representing a curve rather than a straight line relationship between manipulated/disturbance and controlled variables. For example, a nonlinear, curved relationship is often observed between over-fire air dampers and NOx.
- Multiple Input Multiple Output (MIMO): The model must be capable of capturing the relationships between multiple inputs (manipulated/disturbance variables) and multiple outputs (controlled variables).
- Dynamic: Changes in the inputs do not instantaneously affect the outputs. Rather there is a time delay and follow by a dynamic response to the changes. It may take 15-30 minutes for changes in the inputs to fully propagate through the system. Since optimization systems execute at a predetermined frequency (e.g., an optimization cycle commencing every 10-30 seconds), the model must represent the effects of these changes over time and take them into account,
- Adaptive: The model must be updated at the beginning of each optimization cycle (e.g., every 10-30 seconds) to reflect the current operating conditions of the boiler.
- Derived from Empirical Data: Since each boiler is unique, the model must be derived from empirical data obtained from the power generating unit.
Cost of Fuel=C Fuel=46.00($/ton)
Cost of Ammonia=C Ammonia=295.00($/ton)
Cost of NOx Credits=C Nox=2500.00($/ton)
L=A Coal *B Eff *S Eff (1)
L=245*0.91*0.38=84.7
84.7=A Coal *B Eff*0.38
222.95=A Coal*BEff (2)
A Coal=222.95/B Eff (3)
where CFuel represents the cost of coal per ton.
The cost of coal (per hour) is expressed in terms of a controlled variable (i.e., boiler efficiency BEff) in
Tons of NOx from SCR=2.504*NOx SCR /B Eff
where NOxSCR is the emission rate from the SCR in lb/mmBtu. The cost of emitting the NOx from the SCR per hour is given by the following:
Cost of NOx per hour=Cost of NOx credits per Ton*Tons of NOx per hour
Given a cost of $2,500 for the NOx credits, the cost of emissions per hour is:
The cost of the ammonia used to remove the NOx is given by:
Cost of Ammonia per hour=Cost of Ammonia per Ton*Tons of Ammonia per hour
Given a cost of $295 per ton of ammonia, the cost of ammonia per hour is:
Cost of Ammonia per hour=295*(NOx Boiler−NOx SCR/BEff
Cost=(10,255+295*NOx 1,Boiler+5965*NOx 1,SCR)/B 1,Eff+(10,255+295*NOx 2,Boller+5965*NO2,SCR)/B 2,Eff
where NOx1,Boiler is the NOx outlet from
